-compound or element, and has special re erence to such a compound or element for use in connection with a heater orother de'-v vice in the heating `of chemicals for disinfecting, as well as for the heating of other goods or materials therein, and for other purposes. d

The object of m invention is to provide a cheap, simple an etlicient heat producing com ound or element which will overcome the claims.

Ipurposes intende quired, and will prevent a ll liabilit of any accidents or injury to the person andlingH the orming of anyl flame when used for the will 've the heat rethe same or to the premises in'which it is used. d

My invention consists, nerallystated, in the novel combination o? materials for the `heat producing compound oralement, as hereinaftermore specifically set forth and described ,and

particularly pointed out iii To enable others skilled in the art to which my invention'appert'ains tomake and j use my improved heat producing ,compoundor element, I will describe the same more fully, referring to thel accompanying drawin, in which- A igure 1 is a vertical central section of a heating device fordisinfecting, in which my improvedl heat producing compound or ele- .ment is contained therein. Fig. 2 is a top view of the device with the coverofl the inner receptacle removed. Fig.`3 is a detail 'sectional view` of the device shmviiigjanother. form1 of the isame.

Like symbols of reference herein indicate parts in eachl of the figures of the drawing.

As illustrated inthe drawing, my improved heat producing compound or element is shown in connection with a heater AI for I ,disinfectin1 whichv is preferably of. tin 'or other suita e thin sheet metal vhaving the cup-shaped @iter portion 1 to form the outer receptacle 2 for the heat producing compound o'r element hereinafter-described,iand

Pennsylvania, haveformed `o tween the angesl'O Patented Dec. 5, 19i1`.

the cup-shaped inner Vportion 3 to form the inner rece tacle 4 forl the disinfectant or other (goodp scribe The. inner receptacle 4 extends into the outer receptacle 2, so as to form a space 5 between the bottom or Alower endl of the same and the bottom or lower end of said receptacle 2,- and such receptacle `4 is preferably carried by and forms part of a lid or cover 6 for-said receptacle 2. This cover 6 is provided with an annular recessy or depression 7 around the same, and inthe bottom` or wall 8 forming said depression are formed thin indented ortions 7', while the outerwal'l 8 of said epression.y is inclined outwardly for engaging lwith an inwardlyextending like-shaped portion 9 on a flange 10 at the upper endof the/receptacle 2, and a fian e 1,0 on saidcoverand at the upper end o the inclined wall 8. is adapted to fit over Athe flange' 10.

In the use of the\heat producing compound or element for the heating ofthe oods or chemicals inlv the heater A, such as or disinfect-ing pur oses, such heaterhas the heat aluminum and an alkali-metal hydrate, such as caustic alkali in a d state, which are placed Within the receptac e 2 by locatinga mass or block 11 of said aluminum and of about an ounce in wei ht in the `space 5 between said receptacle an the bottom of said rece tacle4, such block being held in pla'ce, i desired, in any suitable manner, or by any suitable means on the receptacle 2, and "over and around said block,

such as at 12, the dry caustic alkali of about three Ounces in weight, is placed. If de# sired, the `blockf11 can be held in place in the space 5'by a iange 4 on the receptacle 2 and extending'below the bottomh of the same,

as shown in Fi 3. The receptacle 4y is then placed within the rece tacle A2, which will allow the caustic a ali to extend aroundv the same, and the receptacle 4 is inclosed by thecover 6 surroundin lthe said receptacle 4, which isy also secure to said receptacle 2 by suitable pressure uponf the.

same, so that the inclined wall 8 on said cover-is firmly pressed down onto. the in y -'clined flange portion 9 on the .receptacle 2' to hold the same. in place, and if desired, the said receptacle 2 and said lcover can be hermeticall sealed together by soldering besuitable manner.

s to be heated, as hereinafter de and 10 or in any otherproducing onfipound or element The matter to be heated is placed within the receptacle 4,.such as a disinfectant, as shown at 13, and it is inclosed therein by a lid or cover 144 placed and secured over the upper end of said receptacle. When the parts are thus assembled, the heater A is ready for use, and all that is necessary is to remove the cover 14 from the receptacle 4, punch holes, such as is shown at 15, through the thin indented vportions 7 in the wall 8 forming the bottom of the depression 7 in the cover 6, and after this is done a sulicient quantity of water and of about eight ounces is poured into the said recess, and such Water in passing through such holes will contact and mix with the caustic alkali 12 and the aluminum block 11. The action of `such water on the compoundl or ,element period, and any gases or vapors generatedl in the receptacle 2 will pass out the vents formed 'by the holes 7 in the cover 6, while the gases or vaporsgenerated from such disinfectant can pass out of the top of the receptaclel and into the room or apartment to be disinfected.

It will thus be seen that my improved heat producing compound or element can be used in heaters or other similar devices for. disinfecting and for other purposes with perfeet safet and being lameless'will not be liable to amage or cause injury or burning of persons handling the same or to the room or apartment in which it is used, as would be the case with the ordinary forms of disinfecting devices employing fuel which emits llames for heating the same.

It will be obvious that various materials for being vaporized can be used for being heated by my improved heat producing compound or element in disinfecting, and that the same can be used for heating other materials, objects and articles, as Well as heating any ofits advantages.

What I claim as my invention and desire to secure by Letters Patent is ,1. A heat generating compound composed of aluminum and dry caustic alkali.

2. A heat generating compound composed of a block of aluminum and dry. caustic alkali.

3. A heat roducing element comprising the combinatlon `of an alkali-metal hydrate and aluminum;

4. A heat roducingelement comprising the combination of an-alkali-metal hydrate and aluminum in the form` of a unitary mass.v

Intestimony whereof, I, the said ABRA- HAM S. IsAAcs, have hereunto set my hand.
